I have the HSM MKII. It's a great lens. I love the size, the IQ and the fast focus. I have the 80-200 AF-S to use with my D600, but don't like it as much as the 50-150mm I think about seling the 80-200mm and use the money to buy a D7100 to be used with the 50-150mm. I used the lens mostly for sport and concert photography. This is a good buy for sure.

I can show you some pictures taken with it, but you don't realy need to see them, the lens is good !!
